最后的结果gdb调试结果为:
[New LWP 5070] Core was generated by `8, 6238, 6768, 6414, 5857, 6219, 6774, 5642, 5099, 6080) (gdb) frame 0 #0 0x00007fa69aa8f17c in ___vsnprintf_chk (s=0x7ffcb1275ffa ", 5347"<error: Cannot access memory at address 0x7ffcb1276000>, maxlen=<optimized out>, flags=1, slen=<optimized out>, format=0x55e0aef3a657 ", %d", args=args@entry=0x7ffcb0e28c00) at vsnprintf_chk.c:66 66 in vsnprintf_chk.c (gdb) frame 1 #1 0x00007fa69aa8f095 in ___snprintf_chk (s=<optimized out>, maxlen=<optimized out>, flags=<optimized out>, slen=<optimized out>, format=<optimized out>) at snprintf_chk.c:34 34 snprintf_chk.c: No such file or directory.

()以上结果说明在writeResult函数中出现了段错误.
利用thread apply all bt full查看每个线程在堆栈中的使用情况.
GDB过程中最重要的几个指令为:
0. gdb core-CodeCraft-2019.5070.jl.1554081713 1. set solib-absolute-prefix / 2. set solib-search-path / 3. file 可执行文件 4. core-file core-CodeCraft-2019.5070.jl.1554081713 5. frame 2Linux公社的RSS地址：https://www.linuxidc.com/rssFeed.aspx
